Hi,
You could use Nedi <http://www.nedi.ch/>which works also on windows or
option is to use WIR3D <http://wir3d.sourceforge.net/> under vm machine.

You could also use Netdisco, which would build the DB for you.

 Interesting thought: I wonder if I could pull the spanning tree tables
off my switches via SNMP and use them to build a database of port to MAC
connections. I already have a table of all the user workstations' MAC
addresses.

Two options I see:

Make a matrix of mac addresses to jack number/office numbers and then
look at the switch's CAM table.  You'll then see what port goes to what
office.

If the switch is running spanning tree, you could sniff each port and
look at the source MAC of the BPDU.  This should be the MAC address of
the connected switchport.
